Other Parts Discussed in Thread: LM3478,
Is it possible to use the TPS6104x in a flyback configuration, similar to this?
We need 60-200V range for APD bias. Load current is <1mA. Output ripple is not a major concern, we can filter higher harmonics with a 2nd stage RC filter.
The transformer would be 1:10 ratio, something like TDK ATB Series.
